APPARATUS FOR FINISHING THE MOUTHS F GLASS BOTTLES.

Application filed May 18, 1915. Serial No. 28,954.

, provements in Apparatus for Finishing the Mouths of Glass Bottles; andI do hereby declare the following to be a full, clear,'and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked therein, which form a part of this specification.

The present invention has for its object a finishing machine for themouths of glass bottles, or other similar glass vessels, espe ciallyintended for rendering as regular as possible the position and the shapeof the mouths before the bottles are removed from the mold in which theyare blown.

The proper. action of this machine is to dispose the material of thebottle neck in equal thickness against the wall of the mold, to give tothe mouth its definitive dimensions, a regular conical shape and afinish sufficient for the stoppering with a cork.

By means of this improved machine, it is possible to obtain theseresults without ex-' cessive expenses for wages or mechanical power.

Another advantage of this machine is that all the bottles of a same setare made quite similar.

These results are obtained by using a conical rotary tool supported by aframe in such a manner that it can be moved and arranged without gropingin the right position in a line with the axis of a bottle mouth and thenmoved parallelly to said axis so as to be brought into contact with thematerial of the bottle neck. This parallel mo' tion is also suitablylimited according to the dimensions to be given to the mouth. When thetool is removed from its position in a line with the axis of the mouth,it is carried away without groping onto a flame, the function of whichis to heat the tool and at the same time to cover it with lamp-black.

It has also been found advantageous to provide the conical tool withgrooves arranged along generating-lines'of the cone; the Work done witha grooved tool is more Specification of Letters Patent.

The drawings show by way of example a preferred embodiment of theinvention.

Figure 1 is a side view of the machine- Fig. 2 is a partial view frombehind;

The conical tool 1 is secured by any suitable ni'eans to the verticalrotary shaft 2 journa'led in bearings 3 and 4: of a frame 5 and drivenby means of a flexible shaft 6. The vertlcal shaft 2 is also adapted toslide longitudinally in the-bearings 3 and 4, but it is prevented fromsliding down by alever 7 turning upon a pivot 8 of the frame,

the arm 7 of said lever, which terminates in a handle, surrounds acollar 9 adapted to turn without sliding upon the shaft 2' and providedwith two pins 10 which pass through slots 11 in the lever 7. The otherarm of said lever is provided with a counterweight 36, the position ofwhich on the lever can be altered in order to balance the weights ofshaft 3, shaft 6 and fittings. When sliding upward in its bearings, thevertical shaft 2 is stopped by the bearing 3 and in the other directionby a piece of fiat-iron 12 bent at right angle, the hori zontal part ofwhich is provided with a hole through which the shaft passes. In thevertical part a vertical slot is provided through which passes ascrew-threaded pin 13 secured to the bearing 1. The piece 12 can by thisway be secured at any desired height by means of a nut 1 1. India-rubberor other elastical buffers 15 are arranged on both sides of the collar9.

The frame 5 is provided with a sleeve 16 adapted to slide and to rotateon the vertical post 17 supported by the base-plate 18; this sleeverests'by the interposition of ball-bearings on a collar 19 that can besecured at any required height on the post 17 by means of a screw 20terminating in a handle; the end of said screw is guided in a groove 21of the post. The sleeve 16, which revolves on the collar 19, can'besecured to the same in four distinct positions. Therefore, the collar isprovided with four bolting-notches such as 22 and 22' arranged at 90 onefrom the other on the periphcry" of the collar. Sliding in alongitudinal groove of the sleeve 16 is mounted a bolt 23 provided witha pivot 24' passing through the slot 25 of a lever 26. -Said lever issecured to a shaft 27 journaled in bearings 28 of the frame andterminating in a handle 29. By lifting said handle 29, it is possible tolift the bolt 23 out of the bolting-notch, so that the sleeve 16 and theframe 5 is allowed to turn freely. The bolt 23 is inclined to fallautomatically into the notches of collar 19 by the weight 30; it ispressed in the groove of the sleeve 16 by a spring 31.

In the base-plate 18 is a hollow 32 adapted to contain the bottom of themold 3-3 in such a manner that the axis of the mold is in a line withthe axis of the tool 1 when the bolt 23 has been forced into the notch22. Upon the base-plate 18 is also secured an oil lamp 34- or a Bunsenburner with lighting-flame. Said lamp is arranged in such a positionthat the vtool 1 is carried exactly into the flame when the frame isturned-and the bolt 23 forced into the notch 22. The function of thisflame is to heat the tool 1 and to cover it with lamp-black during thetime that the frame is turned so as to clear the access tothe mold. Theapparatus being in this last described position, with the tool 1 in theflame, the glass is introduced in the mold- 33 and blown into a bottle;but it must be noted that after this operation the mouth of the bottleis always rather irregular. By operating the handle 29, the workmanrenders the frame free and turns the same, bringing the tool 1 over-themouth. When theexact position of the tool 1 is attained, the bolt 23falls into the notch 22 and locks the frame 5; the workman then movesthe handle 7 down and the rotary tool 1 is driven into the mouth of theneck for finishing the 7 same.

the .cone. These grooves are numerous and without sharp edges, so thatthey do not scrape out glass from the mouth.
